FRANK IBERT, OF NEW YORK, N. Y.

PIPE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 653,677, dated July 17, 1900.

Application led April 10, 1900. Serial No. 12,287. (No model.)

lb all whom it may concern.-

Be it known that I, FRANK IBERT, a citizen ofthe United Staates, and a resident of New York, (Brooklym) county of Kings, and State of New York, have invented cert-aiu new and useful Improvements in Pipe Nozzles, of which the following is a specification.

This invention relates to a nozzle for steampipes which is so constructed that it will break the force of the steam ejected. To effect this, I arrange within the nozzle a con- Volute web, which deflects the steam and causes it to assumeaspiral course before issuing from the nozzle.

In the accompanying drawings, Figure lis a longitudinal section of my improved pipenozzle, showing it applied for injecting steam into a water-tank. Fig. 2 is au end view of the nozzle, and Fig. 3 a longitudinal section of a modification.

The letter ct represents the tubular shell of the nozzle, open at both ends and adapted to be coupled toa steam-pipe b. Within the shell a is contained a spiral web c, which forms a convolute passage between its threads. The shell ct projects at its discharge end ct' beyond the end of the web and is provided, preferably, with an inclined lateral slot a2, arranged substantially in the direction of the convolute thread. As the steam passes through the vnozzle it is deflected from a straight or direct into a tortuous course, so that its force is broken, and that it will issue from the nozzle in a gentle stream.

The drawings show the nozzle d projecting into a tank A below the Water-level thereof and in which the Water is to be heated by the steam, such and similar tanks in the form of steaming-tanks, mash-tubs, cookers, dto., being used by brewers. Heretofore with this class of vessels the steam would frequently issue in so violent a form that the building would shake and that the dierent parts of the apparatus would soon Work loose. Vith my invention these objections are overcome and a quiet admixture of the Water With the steam without noise or rattling is assured. The lateral slot c2, which is submerged, serves to permit some of the steam to escape laterally into the water, so that the body of the steam is subdivided and its force is thus still more broken.

In Figs. l and 2 the convolute web is shown to be fixed and to be attached directly to the inner face of the shell d. In Fig. 3 it is made rotatable,being provided with a shaft c,h ung in radial bearings d, that project inwardly from the shell ct.

Although the invention is shown to be applied to a liquid-tank, I do not wish it to be understood that I limit myself to such use. Thus the invention may be applied to steampipes for radiators and, in fact, to any noz'- zle from which steam issues and within which the force of the jet is to be broken.

Vhat I claim is-Y l 1. A pipe-nozzle composed of a tubular shell and a convolute web within said shell, the discharge end of the shell projecting beyond the convolute web and being provided with a lateral discharge-slot, substantially as specified.

2. The combination ofa tank with a tubular nozzle opening into the same below the water-line, a convolute web within the nozzle, and a steam-pipe to which the nozzle is coupled, substantially as specified.

Signed by me at New York city, county and State of New York, this 9th day ofApril, 1900.
